Mars MEI 2400 Series Bill Acceptor Repair – 2451

posted in: Bill Validators, Repair

The MEI 2400 bill acceptor/validator was rejecting bills.
It did not appear to be the belts, cleaning, etc. Based on it’s symptoms, it had to be something in the logic. It would accept the bill, pause, then return the bill to you. It would not not forward it to the stacker.
Found the 470/35 electrolytic to be the culprit It was leaky, & vented. Problem solved.
Will keep the belt kit aside.
